'Principalities' in the Bible

For I am convinced [and continue to be convinced—beyond any doubt] that neither death, nor life, nor angels, nor principalities, nor things present and threatening, nor things to come, nor powers,

So now through the church the multifaceted wisdom of God [in all its countless aspects] might now be made known [revealing the mystery] to the [angelic] rulers and authorities in the heavenly places.

When He had disarmed the rulers and authorities [those supernatural forces of evil operating against us], He made a public example of them [exhibiting them as captives in His triumphal procession], having triumphed over them through the cross.
